Chapter 19.1, Problem 7LC

a.

Interpretation Introduction

Interpretation : Determine whether the acid is monoprotic, diprotic, or triprotic.

Concept Introduction : Ionizable ions are those where the hydrogen atom can form a hydrogen ion. The ionizable acids are classified as monoprotic, diprotic, and triprotic acids depending upon their number of ionizable hydrogen ions.

Answer to Problem 7LC

The acid ${\text{H}}_{\text{2}}{\text{CO}}_{\text{3}}$ is a diprotic acid.

Explanation of Solution

The acid is ${\text{H}}_{\text{2}}{\text{CO}}_{\text{3}}$ . It has two ionizable hydrogens.

The acid is classified as diprotic acid where protic means proton hydrogen ion and di means two.

b.

Interpretation Introduction

Interpretation : Determine whether the acid is monoprotic, diprotic, or triprotic.

Concept Introduction : The quantity of hydrogens that can combine to create ionizable hydrogen ions differs among Arrhenius acids. The ionizable acids are classified as monoprotic, diprotic, and triprotic acids depending upon their number of ionizable hydrogen ions.

Answer to Problem 7LC

The acid ${\text{H}}_3{\text{PO}}_4$ is a triprotic acid.

Explanation of Solution

The acid is ${\text{H}}_3{\text{PO}}_4$ . It has three ionizable hydrogens.

The acid is classified as triprotic acid where protic means proton hydrogen ion and tri means three.

c.

Interpretation Introduction

Interpretation : Determine whether the acid is monoprotic, diprotic, or triprotic.

Concept Introduction : The quantity of hydrogens that can combine to create ionizable hydrogen ions differs among Arrhenius acids. The ionizable acids are classified as monoprotic, diprotic, and triprotic acids depending upon their number of ionizable hydrogen ions.

Answer to Problem 7LC

The acid $\text{HCl}$ is a monoprotic acid.

Explanation of Solution

The acid is $\text{HCl}$ . It has one ionizable hydrogen.

The acid is classified as monoprotic acid where protic means proton hydrogen ion and mono means one.

d.

Interpretation Introduction

Interpretation : Determine whether the acid is monoprotic, diprotic, or triprotic.

Concept Introduction : The quantity of hydrogens that can combine to create ionizable hydrogen ions differs among Arrhenius acids. The ionizable acids are classified as monoprotic, diprotic, and triprotic acids depending upon their number of ionizable hydrogen ions.

Answer to Problem 7LC

The acid ${\text{H}}_{\text{2}}{\text{SO}}_4$ is a diprotic acid.

Explanation of Solution

The acid is ${\text{H}}_{\text{2}}{\text{SO}}_4$ . It has two ionizable hydrogens.

The acid is classified as diprotic acid where protic means proton hydrogen ion and di means two.
